Description

Fatigue prevention device

technical field

The invention belongs to the technical field of safe driving, and in particular relates to a device for preventing fatigue driving.

Background technique

With the increase of the number of cars every year, the driving safety of cars has been paid more and more attention by people, and fatigue driving is one of the important hidden dangers of today's traffic safety. When the driver is tired, his ability to perceive the surrounding environment, judge ability and control ability of the vehicle will decrease, so it is easy to have traffic accidents.

Especially when driving on long distances and highways, the driver's attention is always in a state of high mental tension, and with the continuous improvement of speed and the prolongation of driving time, the driver will appear fatigued. Driving on the expressway, the road environment is single, the traffic interference is less, the speed is stable, the noise and vibration frequency in driving are small, it is easier to make the driver feel monotonous and drowsy, and hypnotic phenomenon occurs. This can easily cause serious traffic accidents.

Therefore, it is urgent to develop a device for reminding the driver who may be in a fatigued state.

Contents of the invention

In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide an easy-to-use and fast-response fatigue-prevention driving device.

In order to achieve the above object, the technical scheme adopted in the present invention is as follows:

The device for preventing fatigue driving includes a sensor, an ECU and a loudspeaker; the sensor is embedded on the front windshield of the car to monitor the driver's eye-closed time, and transmits the eye-closed time information to the ECU; the ECU is set in On the instrument panel, it is used to judge the information of the eye-closing time, and when the eye-closing time is longer than the set threshold, a warning message is sent; the speaker is connected to the ECU, and is used to send out a warning sound when receiving the warning message .

Further, the ECU is provided with a sensor control module for controlling the operation of the sensor.

Further, it also includes a flashing light control module, the said flashing light control module is respectively connected with the ECU and the taillight of the vehicle, and is used to issue a double flashing instruction to the taillight of the vehicle when the warning information is received.

Further, the whistle control module is also included, and the whistle control module is respectively connected with the ECU and the car horn, and is used to issue a whistle command to the car horn when receiving the warning information.

Further, a sensor indicator light is also provided on the automobile instrument panel, and the sensor indicator light is respectively connected with the sensor and the ECU for displaying the working state of the sensor.

Further, the sensor is inlaid on the left side of the front windshield of the car.

Further, the threshold value is 1s.

Compared with the prior art, the present invention has the following beneficial effects:

1. When the sensor is working, the indicator light of the sensor is on to monitor the driver's eyes in real time. If the driver closes his eyes for more than 1 second, the loudspeaker will sound a sharp alarm and remind the driver to stop and rest. Greatly improved driving safety.

2. Through the flashing light control module and the whistle control module, the double flashing and whistle can be turned on, which can remind the surrounding vehicles or pedestrians, and avoid traffic accidents.

3. The present invention can make a reminder within 1 second, respond quickly, and can avoid the occurrence of traffic accidents to the greatest extent.

detailed description

The present invention will be described in further detail below in conjunction with specific embodiments.

As shown in Figures 1 and 2, the device for preventing fatigue driving includes a sensor 1, an ECU 7 and a loudspeaker 10; The eye duration information is transmitted to the ECU7; the ECU7 is arranged on the instrument panel 11 for judging the eye closure duration information, and sends a warning message when the eye closure duration is greater than a set threshold; the loudspeaker 10 and the ECU7 Connection, used to make an alert sound when an alert message is received.

When sensor 1 works, the situation of eyes 9 can be monitored in real time, if the driver's eyes closed time is greater than the threshold value, then connect loudspeaker 10 and send a sharp alarm sound to remind the driver to stop and have a rest.

As an optimization, a sensor control module 6 is provided on the ECU 7 for controlling the operation of the sensor 1 . The sensor control module 6 controls whether the sensor 1 is turned on or not, so as to switch between working and non-working states.

As an optimization, it also includes a flashing light control module 5, which is connected to the ECU 7 and the taillights of the car respectively, and is used to send a double flashing instruction to the taillights of the car when warning information is received. Turn on the double flash to remind the cars or pedestrians behind.

As an optimization, the whistle control module 8 is also included, and the whistle control module 8 is respectively connected with the ECU 7 and the car horn, and is used for sending a whistle command to the car horn when receiving warning information. Horn can alert surrounding vehicles or pedestrians.

As an optimization, a sensor indicator light 3 is also arranged on the automobile dashboard 4, and the sensor indicator light 3 is respectively connected with the sensor 1 and the ECU 7 for displaying the working state of the sensor 1 .

As an optimization, the sensor 1 is inlaid on the left side of the front windshield 12 of the automobile. Since the driver's cab of a domestic car is on the left side, the binocular eyes of the driver can be better monitored because the monitoring area of the sensor 1 is triangular.

As an optimization, the threshold value is 1s. Because people blink more than 10 times per minute, and each blink takes 0.3~0.4s, and the interval between each blink is about 2.8~4s. When the time of closing eyes is longer than 1s, it can be judged that the driver has entered a state of fatigue, so It is more appropriate to set the threshold to 1s.

The above-mentioned embodiments of the present invention are only examples for illustrating the present invention, rather than limiting the implementation of the present invention. For those of ordinary skill in the art, other variations and modifications in various forms can be made on the basis of the above description. All the implementation manners cannot be exhaustively listed here. All obvious changes or changes derived from the technical solutions of the present invention are still within the protection scope of the present invention.
